  Structural Optimization and Biological Evaluation of 2-Substituted 5-Hydroxyindole-3-carboxylates as Potent Inhibitors of Human 5-Lipoxygenase

  摘要：

  Pharmacological suppression of leukotriene biosynthesis by inhibitors of 5-lipoxygenase (5-LO) is a strategy to intervene with inflammatory and allergic disorders. We recently presented 2-amino-5-hydroxy-1H-indoles as efficient 5-LO inhibitors in cell-based and cell-free assays. Structural optimization led to novel benzo[g]indole-3-carboxylates exemplified by ethyl 2-(3-chlorobenzyl)-5-hydroxy-1H-benzo[g]indole-3-carboxylate (compound 11a), which inhibits 5-LO activity in human neutrophils and recombinant human 5-LO with IC50 values of 0.23 and 0.086 mu M, respectively. Notably, 11a efficiently blocks 5-LO product formation in human whole blood assays (IC50 = 0.83-1.6 mu M) and significantly prevented leukotriene B-4 production in pleural exudates of carrageenan-treated rats, associated with reduced severity of pleurisy. Together, on the basis of their high potency against 5-LO and the marked efficacy in biological systems, these novel and straightforward benzo[g]indole-3-carboxylates may have potential as anti-inflammatory therapeutics.

  新型AKR1C3抑制剂6-氨基-4-苯基-1,4-二氢吡喃并[2,3 - c ]吡唑-5-甲腈的筛选，合成，晶体结构和分子基础

  摘要：

  AKR1C3是去势抵抗性前列腺癌的有希望的治疗靶标。在本文中，对内部文库的评估发现取代的吡喃并吡唑是AKR1C3抑制剂的新型支架。初步的SAR探索确定其衍生化合物19d是最有前途的化合物，其IC 50为50在23个合成分子中的0.160μM。晶体结构研究表明，吡喃并吡唑支架的结合方式与目前的抑制剂不同。C4-苯基取代基上的羟基，甲氧基和硝基一起将抑制剂锚定在氧阴离子位点上，而支架的核心则显着增大，但部分占据了具有丰富氢键相互作用的SP口袋。令人惊讶的是，该抑制剂经历了构象变化，以适应AKR1C3及其同源蛋白AKR1C1。我们的结果表明，在合理设计选择性AKR1C3抑制剂时，应同时考虑受体和抑制剂的构象变化。从分子动力学模拟获得的详细结合特征有助于最终阐明6-氨基-4-苯基-1的分子基础，c ]吡唑-5-腈作为AKR1C3抑制剂，这将有助于将来合理的抑制剂设计和结构优化。

  Activated primary, secondary, and tertiary amides were coupled with enolizable esters in the presence of LiHMDS to obtain good yields of β-ketoesters at room temperature. Notably, this protocol provides an efficient, mild, and high chemoselectivity method to synthesis of β-alkylketoesters using the cross-coupling between aliphatic amides and esters. Meanwhile, gram-scale secondary and primary amides reacted

  An efficient synthesis of oxacycles and azacycles was developed using a Brønsted base-catalyzed tandem alkyne isomerization–Michael reaction sequence. Functionalized 2-alkylidenetetrahydrofurans were prepared by an intramolecular oxy-Michael reaction on an allene that was generated in situ from an alkynoate. The aza-Michael version using alkynylamines, alkynylamides and alkynyl carbamates led to piperidines

  利用布朗斯台德碱催化的串联炔烃异构化-迈克尔反应序列，开发了一种有效的氧杂环和氮杂环的合成方法。通过在链烯酸酯上原位产生的烯丙基上的分子内氧-迈克尔反应，制备官能化的2-亚烷基四氢呋喃。使用炔基胺，炔基酰胺和氨基甲酸酯的氮杂-迈克尔版本分别导致了哌啶，内酰胺和恶唑烷酮。该反应的对映选择性形式产生具有高对映选择性的轴向手性内酰胺。但是，某些炔烃无法完成分子内迈克尔反应，无法提供对映体富集的烯。

  3-Acyltetramic acids having various substituents at the 1-and 5-positions, and possessing a tricarbonylmethane structure, were synthesized and tested for antimicrobial activity to investigate the structure-activity relationships. It was found that the nature of the substituents at the 1-and 5-positions as well as the 3-position is an important factor for activity to inhibit the growth of Bacillus subtillis and Staphylococcus aureus.

  Cyanophosphates (CPs) can easily be prepared via the reactions of carbonyl compounds with diethyl phosphorocyanidate (DEPC) in the presence of LiCN (cat.) under non-aqueous conditions. Treatment of ketone-derived CPs with TMSN3/Bu2SnO (cat.) in toluene at reflux produces cyclopentenes or heterocyclic products in good yields under neutral conditions. In this two-step transformation, CPs may form tetrazolylphosphates

  在非水条件下，在LiCN（cat。）存在下，羰基化合物与磷腈二乙酯（DEPC）的反应可轻松制得氰基磷酸盐（CPs）。在中性条件下，用甲苯中的TMSN 3 / Bu 2 SnO（cat。）在甲苯中处理酮衍生的CP，可以高产率生产环戊烯或杂环产物。在此两步转化过程中，CP可能形成四唑基磷酸酯，随后对其进行连续裂解以生成亚烷基卡宾，这些卡宾经过[1,5] -CH插入可生成五元化合物。
